WebOct 24, 2005 · The heat flux is calculated from the temperature (T) and meridional wind (v). T = [T]+T', where [T] is the longitudinal average (or more commonly called the zonal mean) of the temperature, and T' is the deviation from that longitudinal average. It is critical that the heat flux ( [v'T']) be calculated from the product of the zonal mean deviations.
WebOct 1, 2010 · The convergence of the eddy-PV flux, which combines effects of the eddy vorticity and heat flux, is known to lead to the acceleration of the mean flow (e.g. Edmon et al. 1980; Robinson 2006).
